To all whom it may concern: 7

Be it known that 1, Few G. Hermann, a. citizen of Germany, and resident of the city of New York borough of Bronx, county of 5 Bronx, and State of New York, have invented a new and Improved Creasing Iron, of which the following is a full, clear, and exact description.

My invention to a ereasing iron 10 and aims to provide new and useful. im-

provements iiiconnection with e'cl'evirlev ct this character. i

- In leather, and other trodes"utilizingtools which are usually heated,- to merlre groove 01' crease intlie finished article, it is a Well appreciated fact that it has been necessary to employ a separate tool for each type of crease which Was to he made. Thus certain creases are merely in the nature of a hair? line While others are relatively broad, anal still others present double lines running parallel to each other. I

Aside from the multiplicity of tools necessery to permit of the type 01 crease desired being made, it is also appreciated that it has been necess'ar to utilize a heating element which would 5 capable of bringing the tool to the temperetnredesired.v

Having these, ob ects'in mind, I have con structed a tool of the nature specified, which will supplant a number of the tools now in. use, in that its ports are capable of being; 21djusted to permit of creases or grooves of different Widths being made,

A further object of ni'yinvention is construction of a device of the-nature specified which shall preferably include poetion of its bodyn heavy cent-heating unit so I that it Wili not he nest-fishery to employ e 40 heatin r'device to brim the tool to the term i is -perature desired. v

' Still another object of my invention is the construction of a. creasing tool or ilroniwhich shall embody. the improvements'ahove set forth, and which shell nevertheless be ex tremely simple in'construction and economical in manufacture. I

Still other objects of my invention will appear in the annexeo SP'cYClfiCljfilOlfl ts? en in connection with the atcacherl drawings which latter present one practice embflffi ment of my invention, and in which;

end of this be? formed in the sho shtnililer 16 for i may cooper-zit connection of the in provided which "incl i I the edge of the hie-toe Tl? co'opcr gather to permit of a groove or crease be ng made, and it will be obvious that by Varying the distance existent between these two t c edges, that a crease of any desired Width may be made, and these elements are retained in assembled position by any suitable means such as a screw 18 extending transversely through both of their bodies.

Now with a view of retaining the edges aforementioned in their proper position it will be noted'that I utilize a wedge 19 preterably constructed in a manner illustrated in Figure 7. This member is formed with a notch 20 to accommodate a screw 18, and a shoulder 21 preferably associated with the blade 17 limits the downward movement of this wedge. Also the inner face of the beveled portion of the shank 11 may be formed with a series of serrations which serve to grip the wedge and prevent any movement of this element with respect to the shank and blade upon the screw 18 having been tightened.

.jhus a tired adjustment is provided, and any amount oi latitude may be allowed to the ranges of adjustment which may be accomplished by simply loosening the screw 18 or other retaining clement utilized, and in moving the wedge to a point at which the edges of the blac e and the shank will be at the desired distance apart, and in subsequently tightening the screw l8, it being also noted that wedges oi varying thicknesses may be employed to permit of one tool being capable of having its parts adjusted to cover any range of work desired.

lit will be obvious that in most instances, an operator would desire to be able to duplicate certain phases of work, and to accomplish this it will be necessary to have the edges of the shank and blade in exactly the same spaced relationship has been utilfeed in the original operation. With a view of permitting this being; done. it will be noted, reference being had to Figures 1, 2 and that in the embodiment illustrated, the tool capable o1 three adjustments. This is permitted by virtue of the fact that the blade is formed with a plurality of V shaped slots 23 through which lugs 24- atl.:'l o the wedge 19 project.

won the lugs being moved to the posisl'niwnin l igure 2, i. e. in which the will contact with the outer end of one each o'l' ots, it will be tn. he as closeeu by this meeseo type of wedge. A release of the screw 18 and movement of the wedge to a point at which these. lugs will rest at the outer end of the opposite arm of each of the slots, as has been indicated in dotted lines in Figure 2, will insure the movement of the blades 17 with respect to the shank ll which will result in the edges of these two members being spaced from one another to their maximum extent, and the intermediate position of these elements may be accomplished by moving the wedge to the position shown in Figure 3 at which the lugs 24 will rest in the crotch ot' the slot.

Thus l have devised a creasing iron the parts of which are constructed in such a manner as to permit of one tool being substituteiil tor a great number of tools, as is now utilized, and furthermme the heating: element described may be associated with this iron, if it is desired to overcome the dilliculties set forth in the preamble of this specification.

()briously numerous modifications of structure might readily be resorted to without in the least departing from the spirit of my invention, which I claim as:

l. A creasing: iron, including a shank ter ininating in an edge, and a blade movably secured to said shank and adjacent the edge thereof. i

2. A creasing iron, including a shank terminating in an edge, a blade movably secured to said shank and adjacent the edge thereof, and means for moving said blade.

3. A creasing iron, including a shank terminating in an edge, a blade movably secured to said shank and adjacent to the edge thercol, and means for normally preventing a movement of said blade with respect to said shank.

4:. A creasing iron, including a shank ten 'minating in an edge, a blade movably se cured to said shank and adjacent to said edge, and a wedge interposed between said blade and shank.

A creasing iron, inchidiug a shank terminating in an edge, a blade movably cured to said shank and adjacent to said edge, a wedge interposed between said blade and shank, and a screw (to-operating will said shank and blade for clamping the same, one to the other.
